Download Biomechanics of the Gastrointestinal Tract Book in PDF, ePub and Kindle
Biomechanics of the Gastrointestinal Tract is an up-to-date book for researchers on the study of the mechanical properties and the motor system of the gastrointestinal tract. A well-illustrated book, it provides a comprehensive overview to relevant tissue geometry, morphology and biomechanical theory. Separate chapters cover smooth muscle and nerve function including the application to animal and human studies of motility, symptoms and pain, determination of the true resting state, history-dependent properties, and tissue remodelling in disease. Several methods and diagnostic applications such as determination of in vivo length-tension diagrams and multimodal pain testing are completely new but will undoubtedly be used by many in the future. New non-invasive imaging techniques based on ultrasound, MR- and CT-scanning in combination with balloon distension are emerging as the techniques for future in vivo studies.

Download Mathematical Foundations and Biomechanics of the Digestive System Book in PDF, ePub and Kindle
Mathematical modelling of physiological systems promises to advance our understanding of complex biological phenomena and pathophysiology of diseases. In this book, the authors adopt a mathematical approach to characterize and explain the functioning of the gastrointestinal system. Using the mathematical foundations of thin shell theory, the authors patiently and comprehensively guide the reader through the fundamental theoretical concepts, via step-by-step derivations and mathematical exercises, from basic theory to complex physiological models. Applications to nonlinear problems related to the biomechanics of abdominal viscera and the theoretical limitations are discussed. Special attention is given to questions of complex geometry of organs, effects of boundary conditions on pellet propulsion, as well as to clinical conditions, e.g. functional dyspepsia, intestinal dysrhythmias and the effect of drugs to treat motility disorders. With end of chapter problems, this book is ideal for bioengineers and applied mathematicians.

Download New Advances in Gastrointestinal Motility Research Book in PDF, ePub and Kindle
Research into gastrointestinal motility has received renewed interest in part due to recent advances in the techniques for measuring the structure and function of gastrointestinal cells, tissue and organs. The integration of this wealth of data into biophysically based computation models can aid in interpretation of experimental and clinical measurements and the refinement of measurement techniques. The contents of this book span multiple scales - from cell, tissue, organ, to whole body and is divided into four broad sections covering: i) gastrointestinal cellular activity and tissue structure; (ii) techniques for measuring, analyzing and visualizing high-resolution extra-cellular recordings; (iii) methods for sensing gastroelectrical activity using non-invasive bio-electro-magnetic fields and for modulating the underlying gastric electrical activity and finally (iv) methods for assessing manometric and videographic motility patterns and the application of these data for predicting the flow and mixing behavior of luminal contents by using computational fluid dynamic techniques. This book aims to provide both an overview of historical and existing research techniques as well as to highlight future directions and challenges for the community as a whole. It will be suitable for clinicians to understand the cellular and biophysical underpinnings of gastric emptying, gastroenterologists, surgeons, bioengineers and all scientists with interests in gastrointestinal motility research.

Download Clinical Mechanics in the Gut: An Introduction Book in PDF, ePub and Kindle
The gastrointestinal tract is a series of organs each with distinct mechanical functions. Each organ within the system brings food contents in the gut lumen to the site of absorption through separate mechanical functions. These mechanical functions are generated by a fine-tuned interaction between neuronal networks and active muscle layers. The passive components of the gastrointestinal wall such as the collagen-rich submucosa also play an important role in these mechanical actions. Clinical Mechanics in The Gut provides a thorough understanding of the anatomy and biomechanics of the physiological function and pathophysiology of the gastrointestinal tract. The book first gives an introduction to readers about the physical geometry of the gastrointestinal tract followed by a detailed explanation of biomechanical theory and its application to approximating and modeling gut mechanics. This is expanded further by detailed explanations of gut muscle and motor nerve functions in proceeding chapters. A biomechanical evaluation of disorders of regulatory mechanisms such as achalasia and Hirschsprung disease and disorders of effector mechanisms such as reflux disease, systemic sclerosis of the gastrointestinal tract and colonic diverticular disease are also included. Readers will, therefore, gain an understanding about clinical problems in gastroenterology from a bioengineering and modeling perspective. Clinical Mechanics in The Gut is a useful reference for gastroenterology researchers, biomedical engineers and systems biologists seeking to understand the physiology of the gut and applying this knowledge to surgical procedures, computer-based modeling systems and robotics.

Download Biomechanics of the Small Intestinal Contractions Book in PDF, ePub and Kindle
The small intestine is a part of the gastrointestinal segment comprising of the duodenum, jejunum, and ileum. They help to process the gastric contents for further digestion, which involves mixing with duodeno-biliary-pancreatic (DBP) secretions to facilitate the chemical digestion, and homogenization of the luminal contents through contractions of the circular and longitudinal smooth muscle fibers of the intestine. The contractions of these smooth muscle fibers develops the mechanical forces at the mucosal wall, which as a consequence, transfers its momentum to the underlying fluid to develop the fluid flows, suggesting relevance of mechanics in physiology. The resulting flows are what drive the digestion. Changes in contractility of wave shapes of circular and longitudinal smooth muscle contractions and fluid rheology are known to affect the digestive process through generation of various flow patterns that differ in luminal pressure, peak velocity, extent of shearing/ mixing, volume of mixing, and flow rate. Recent studies indicate that the digestive process can be very specific such as to cause lipid digestion through segmental contractions and transport by eliciting propagating contractions, suggesting that the intestine manages to digest a variety of food in an efficient manner by eliciting appropriate contractions.

Download The Physical Processes of Digestion Book in PDF, ePub and Kindle
Food research (and funding) is becoming more and more focused on health. While researchers and product developers have made great strides in food engineering, there needs to be increased focus on what happens when the food is actually digested. How is the food absorbed? Do the benefits remain? Digestion is a complex topic, and this will be the first book aimed at food researchers. Authored by a physiologist and a food engineer, the book will be a welcome addition to the literature.

Download The Impact of Food Bioactives on Health Book in PDF, ePub and Kindle
“Infogest” (Improving Health Properties of Food by Sharing our Knowledge on the Digestive Process) is an EU COST action/network in the domain of Food and Agriculture that will last for 4 years from April 4, 2011. Infogest aims at building an open international network of institutes undertaking multidisciplinary basic research on food digestion gathering scientists from different origins (food scientists, gut physiologists, nutritionists...). The network gathers 70 partners from academia, corresponding to a total of 29 countries. The three main scientific goals are: Identify the beneficial food components released in the gut during digestion; Support the effect of beneficial food components on human health; Promote harmonization of currently used digestion models Infogest meetings highlighted the need for a publication that would provide researchers with an insight into the advantages and disadvantages associated with the use of respective in vitro and ex vivo assays to evaluate the effects of foods and food bioactives on health. Such assays are particularly important in situations where a large number of foods/bioactives need to be screened rapidly and in a cost effective manner in order to ultimately identify lead foods/bioactives that can be the subject of in vivo assays. The book is an asset to researchers wishing to study the health benefits of their foods and food bioactives of interest and highlights which in vitro/ex vivo assays are of greatest relevance to their goals, what sort of outputs/data can be generated and, as noted above, highlight the strengths and weaknesses of the various assays. It is also an important resource for undergraduate students in the ‘food and health’ arena.
